On the aether-like Lorentz-breaking actions
M. Gomes, J. R. Nascimento, A. Yu. Petrov +1
We demonstrate the generation of the CPT-even, aether-like Lorentz-breaking actions for the scalar and electromagnetic fields via their appropriate Lorentz-breaking coupling to spi…
Free energy of Lorentz-violating QED at high temperature
M. Gomes, T. Mariz, J. R. Nascimento +3
In this paper we study the one- and two-loop contribution to the free energy in QED with the Lorentz symmetry breaking introduced via constant CPT-even Lorentz-breaking parameters…
On the effective potential in higher-derivative superfield theories
M. Gomes, J. R. Nascimento, A. Yu. Petrov +1
We study the one-loop quantum corrections for higher-derivative superfield theories, generalizing the approach for calculating the superfield effective potential. In particular, we…
The Gödel solution in the modified gravity
C. Furtado, T. Mariz, J. R. Nascimento +2
We consider the modified gravity whose action represents itself as a sum of the usual Einstein-Hilbert action and the gravitational Chern-Simons term and show that the Gödel metric…
On the superfield effective potential in three dimensions
A. F. Ferrari, M. Gomes, A. C. Lehum +4
We develop the superfield approach to the effective potential in three dimensions and calculate the one-loop and two-loop kählerian effective potential in commutative and noncommut…
